Wires is completely off since her head constantly is fixed in a solid state, if you are hanged on wires, even after death, your body would relax and you would fall off in that position she was in, however her head remains constantly in the same position, regardless of what is going on making this death complete bullox.
The truck driver went out for a vending machine fun, he obviously left the handbrake open, which is why we doubt that death, no logical truck driver in a city leaves a car without handbrake on lock, it's in the veins.
the Girl who leapt through window has left her body in a very inelegant manner, considering the rapid death she received her body should fall overand not remain in a slutty manner as she was. I read this as personal hate towards her form the studio guys. If so, I support it

The elevator death is probably the most memorable, and most impossible when physics are in the works, I know, we shouldn't involve real life physics into an anime, but what they shown is complete bullshit. When she is falling inside the elevator that is falling, with he head being the highest point in the elevator and the moment of the slam, her head miraculously slams the floor ? that's a breaking point in physics, since you can clearly see that at the moment of impact her legs are still where they were when the elevator was falling.
Umbrella Corp(se), as we see her losing balance on the stairs and the umbrella falling and opening, with her body being still up in a fairly safe distance, we see the next scene showing her looking into the needle of the umbrella, the viewer is expected to believe the point of penetration would be the eye, but instead we see her entire body hanging on her throat pierced by the needle of the umbrella, with her feet fairly high on the stairs. How come they make umbrella's so damn fucking tough in Japan ? it should have collapsed under the weigh of the body, seriously, I want THAT umbrella!
Bloody Beach Volley Ball game, how did the ball menage to get THAT far in 4 seconds ? And how come the life guard is so close to the beach on his motor boat and WHAT THE FUCK IS HE DOING not watching where he is going to ?
It was explained the victim had a concussion but that does NOT explain how he was slaughtered, that Life Guard just did reverse life Guarding.
Oh My, My, Heart is RACING!
Seriously ? just like that ? it looked like drug poisoning, I seen drug poisoning and overdose first hand, and I seen 4 heart attacks. THAT was not a heart attack, not even a heart failure, if someone has a weak heart, and has a heart failure, the heart just stops, there is no convulsion, no pain from heart. victim of such a thing simply faints after feeling unwell for a bit. If that was a heart attack, then I congratulate on a heart attack at this age, no matter how weak your heart is, that was drug overdose.
The Slasher Teacher Blue:
His bag was having a lot of killy killy tools or that was the heaviest knife in the history of kitchen knives.
More so even when he stabbed himself in the artery he should nearly instantly fall from blood loss because the brain has no blood source at this point, so any action they showed the teacher doing is FALSE and IMPOSSIBLE.
I judge that was the artery from the blood color, if it was a vein, then OH MY GOD! he should have been dead years ago!
The cliff Ride was fairly plausible but it was outside of the town, still, something like this killing someone is insane. The first thing people do when something hits their front window is HIT THE BREAKS!
I thought Japanese were better drivers, I was wrong.
